The fast-charging, intrinsically safe Versaflo™ lithium-ion battery TR 830 is intended for use with the 3M™ Versaflo™ TR 800 series PAPR system.

The battery reaches 90% charge in approximately three and a half hours and features a charge level indicator for easy visual reference. It is engineered for use in potentially explosive athmospheres and features yellow bumpers to help absorb impact.

When equipped with a new intrinsically safe battery (TR-830) and new filter, the TR-800 PAPR assembly has a run time of 6 to 10 hours depending on system configuration used. PAPR runtime will vary based on battery age, filter loading, filter or cartridge selection, and user selected airflow setting. The battery also can provide approximately 750 full charge/discharge cycle equivalents while maintaining 80% of its original capacity, which is 2× times the cycle life of standard non-IS Versaflo™ batteries TR-630 and TR-632.
